i decided i kind of love the giant cluster clock, and i already have small VDO gauges, so i wonder if anyone knows what it takes to set up a "programmable" electronic tach in lieu of the stock cluster one. i have the hall effect sensor and tach amp installed so the electrical signal should be there, just not sure what this aftermarket gauge expects, other than using a windows 95 computer (?!) to set it up.
